Gaia Head Sprite Fix
From Creatures Wikia
The Gaia Head Sprite Fix by LordBlumiere fixes an issue with the original Gaia breed by Lis Morris. When Gaia was spliced with other creatures, or if the head sprite mutated to Geat-G, the game would usually crash with an error that it could not locate any sprites past head sprite 32. This fix gives Gaia the proper amount of head sprites, so the crash will no longer happen.
